    Love this trimmer!
             
    This product must have been designed by a woman (smile). I enjoy doing yardwork and reaping the benifits of having a nice yard, but the trimming has always been the absolute worst! Everything I hate about a gas trimmer has been corrected in this product. Its lightweight (no more aching arms!)and no more pulling and yanking on a cord until I want to scream and throw it across the yard and then having to take it to hubby to start the thing. This trimmer is also durable and can easily handle my large yard. Thank you B&D for designing a trimmer that fits my needs.
    Pros:

    Lightweight; durable; battery operated;

    Cons:

    Have not discovered any cons yet.

    Fantastic Yard Tool!
             
    I purchased this unit to replace an 8 year old B&D corded unit. I was ready to be cord free and thought lithium batteries could be the solution. I read all the reviews and can honestly say that this trimmer exceeded my expectations. I have been doing my own yard work for 40 years and am particular with the equipment I buy. The trimmer performed very good in all conditions. The dual power stages is a great feature. The automatic line feeding works flawlessly and better than competitor models. It is so easy to trimmer quickly, my trimming time has been cut in half and the battery life has been great. I had previously bought the B&D 20-volt hedge trimmer and was so impressed with it's power I purchased this trimmer/edger. Two family members have purchased this trimmer based on my recommendation.
    Pros:

    Dual power settings, automatic line advance, light weight, adjustable handle, and rotating head. Battery life is excellent.

    Cons:

    The price of pre-wound spools is a little expensive.

    Very Good Product
             
    Just bought the lst420 to replace a trimmer that wore me out dragging a cord around! I am impressed with this trimmers over all performance. Light weight and plenty of power. Edger is a tremendous help. I highly recommend this product if your looking for a great little trimmer!
    Pros:

    Light weight, no power cord to drag around and two batteries keep you in power for long enough to do a average size yard!

    Cons:

    No problems so far!

    Best lightweight trimmer I have ever used!
             
    I bought the 20V LST420 trimmer a couple of days ago! I have a 4 cyl larger trimmer but could not use it because of neck and back surgery. After the first use of the LST 420 I had no back or neck pain. It is light and with the two batteries that come with it I have never run out of power. The LST 420 trimmer is everything that Black and Decker advertises it to be!
    Pros:

    Lightweight, adjustable, edger works as advertised. It is a great little trimmer. I love it.

    Cons:

    Nothing so far
